If the polygons are similar, then the top side is equal to one half of the left side.
Since side (x -1) = 8, then x = 9.
Answer:
x=5
Step-by-step explanation:
x+7=12
x=12-7
x=5
The two points have the same y coordinate, which means that the line is horizontal, which means that the slope is 0.
So, the equation is y=4
The answer is x = 6
To solve this you would use the pythagorean theorem which is a^2 + b^2 = c^2
In this problem a = x b = 8 and c = 10
You would then square these numbers
x^2 + 64 = 100
Next, you would subtract 64 from both sides.
x^2 = 36
All that’s left is the find the square root, which is x = 6.
So, therefore, you’re answer is x = 6
